What downpipe flange is this?
 

Shall have designed a Downpipe for my Garrett (T25 .48?) But which flange is this?

Almost every T25 i've seen have a flange like this, why is my different and is it better or worse?

Well there is no picture so I can't tell you exactly what it is, but more then likely you bought a T25 with a mitsubishi flange on it. Most T25 setups are designed around the flange used by Nissan. Personally I would get a new turbo.

Picture should work now.

Looks kind of like the old cosworth t3 output flanges.

Design is arguably better than a 'standard' t25 as the wastegate outlet angle is better. You'll essentially use a 3 bolt 'floating' flange that will sit over the end of a swaged out 'socket' type joint on the downpipe inlet. Bolting it down will compress it for a leak free seal without a gasket. You can get the 'socket' from mandrel-bends.com. Check their 'socket joint' section. You could probably also get away with a transition cone, but I'm not positive.

Tell us more about that cast exhaust manifold.

Looks like something made for a FWD applications?

I bet money it's the HKS B6 manifold.

Been looking for one for a long time....

There is no way that that manifold is attached to a miata.

Are you sure?

I do not really know much about either manifold or turbo as I bought the kit as it is here - seller stated that it was bought for his now sold NA 1.6.

I am myself quite new to this turbo world, and this is my first turbo build.

Appreciate all help. :bigtu:

Post pictures of the manifold. I'm sure it's a HKS 1.6 turbo manifold.

Looks like this, right?

That appears to be a 3 bolt flange from a Saab. You can also get tdo4's off newer Saab's with a t25 inlet and that same 3 bolt outlet.

viperormiata: Looks like thats the one, yes.

The first 2 pictures you took were with the manifold off the car correct? Hence why I said it is not attached to a miata. If it was bolted on you could not get that picture of the rear flange. No room to get a camera between firewall and turbo and get a perfect picture.

Oh i see. Then I misunderstood you :giggle:

No it is not fitted yet because I just bought it 1 week ago, thats why I signed for this forum to get some good advice, tips and tricks. This is my first turbo build, so its great with a forum like this, have already learned a lot just by reading around the different threads. :ugh2:

Say something now, biatch :hustler:

If you ever decide to sell that manifold, I will throw moneys at you. It's a great piece.

viper, rate this manifold

Sorry to resurrect a old thread
 

I have the exact same kit. But am installing it on a 1.8 with a appropriate manifold of course. Did it ever get sorted on what that flange was? BTW I am selling the 1.6 manifold. The manifold pictured came with the "kit"
